Stretching across a wide range of North Africa with large dunes lies the world’s largest desert: the Sahara Desert. Temperatures in this region can rise to 131 degrees Fahrenheit.
The desert is very humid, it usually has clear skies and hot winds. Due to extremely high temperatures and infertile land, the Sahara is not an ideal location for gardening. Nomads wander around the desert until they reach an oasis where it is possible to farm and cultivate crops in these areas. While some regions are fertile, these lands often become very dry over time. This eventually leads to malnutrition in animals, damaged grasslands, and ineffective pesticides.
There are also problems with fertilization and plowing in the Sahara. Native plants typically have to be removed for farming and there is only a limited water supply for areas of land. To add on, windstorms often rip up plants from the ground. Furthermore, humans have contributed to land infertility with improper farming techniques, leading to more losses in native plants and the expansion of the barren desert. This process is called “desertification.”
While the great Sahara Desert is an astounding environmental climate to learn about, it is important to recognize some of the issues that continue in this region of land. More importantly, farming techniques must be improved to allow for the growth of native plants and support communities while limiting the expansion of the desert.
